US 11,038,493 B1 · Local oscillator (LO) for wireless communication

Abstract

Certain aspects of the present disclosure provide a local oscillator (LO) for wireless communication. In some examples, the LO is configured to generate an LO signal by inverting, by a first inverter, a first signal to generate a second signal having a first frequency, the first signal being an oscillating signal. In some examples, the LO is configured to control, using a third signal having a second frequency, a first switch receiving the second signal. In some examples, the LO is configured to control, using a fourth signal having the second frequency, a second switch receiving the second signal, wherein the fourth signal is a complement of the third signal and wherein the second frequency is one-half the first frequency.

Dependent claims

A local oscillator (LO) generation circuit comprising:

a first oscillator circuit comprising:
a first inverter;
a first switch having a first terminal coupled to an output of the first inverter and a first control input configured to receive a first control signal;
and
a second switch having a second terminal coupled to the output of the first inverter and a second control input configured to receive a second control signal, the second control signal being a complement of the first control signal, wherein a first signal communicated from the output of the first inverter is characterized by a first frequency, wherein the first control signal and the second control signal comprise a second frequency, and wherein the first frequency is divisible by the second frequency.
